I have an early version Italianicon M1A1icon stock, when they were sold by Navy Arms. Mine fits my M1 carbine action perfectly. The main difference from the original is that mine is made from much better wood. Also, the hardware has some minor differences from the "real McCoy", but f/what I paid, less than $100, it's okay. I don't think I'd pay the asking price today, but that's just me. Bottom line: Not the real thing, but pretty neat.
